CAR-AXLE BOX.

SPECIFICATION forming part of Letters Patent No. 242,841, dated June 14,1881.

Application filed March 24,1881. No model.)

T 0 all whom it may concern:

Be it known that I, ANTHONY G.PAUL,J1., of Baltimore city, State ofMaryland, have invented certa-in new and useful Improvements in(Jar-Axle Boxes; and I hereby declare the same to be fully, clearly, andexactly described as follows, reference being had to the accompanyingdrawings, in which- Figure l is a central vertical sectional view of thebox, the axle and brass being shown in elevation; and Fig. 2 is acentral horizontal sectional view of the device.

My invention relates to axle-boxes forrailway-ca-rs; and it has for itsobject to provide an end bearing for the axle, designed to limit thelongitudinal motion of the same and obviate the wear of the shoulders ofthe axle and brass which has heretofore resulted from the usualconstruction and arrangement of these parts.

In the act onipanying drawings, 1 is the axle, and 2 the box, the latterbeing provided with the usual hinged cover and boss 3, that secures thebrass 4. The construction of the entire device, as shown, except inregard to certain particnlars, hereinafter more particularly pointedout, is of the usual standard Baltimore & Ohio pattern. The flange onthe end of the axle isner face of the boss 9. The distance between endof the axle is exposed.

the dovetail conformation of the bossto the front of the box, and bythebolt-fastenings at either side, so that breakage is practically outof the question. The liability of its occurrence is manifestly much lessthan with the usual fornii'of box, as in the latter the. resistancenamely, that of the brasses on the shoulders of the axleis above thelineof thrust, whereas with my device it is opposite the same.

The bearing 5 may be readily removed for renewal, it being onlynecessary to unbolt the face 7 and slide it out of its guides, when theThe improvement possesses one feature of paramountim portan ce.

It involves 11o revolution of the construction of the box, but'isreadily applicable to those in ordinary use.

Having-thus described my invention, what I claim is-- 1. In combinationwith the axle having slots in its terminal collar, the removable bearing5, having lugs 6, and the boss 9, as set forth.

2. In combination with the axle having slotted terminal collar, andbearing5,provided with lugs 6, the box having front plate, 7, anddovetail boss 9, bolted to the box, as set forth.
